Microsoft begins official Windows 10 Mobile rollout for WP8.1

Following several reports giving March 17 as the official Windows 10 Mobile rollout date, the company has just posted the official announcement. Microsoft has announced Windows 10 Mobile release and has also started delivering the operating system to select Windows Phone 81 devices, as the “same-day availability” was hinted at earlier. Users will have to update Windows 10 Upgrade Advisor app on their devices first to get the latest updates. Wondering if your Windows Phone 8.1 has made it to the first wave? In its statement (shared below), Microsoft points to a page with list of devices, but we can’t see anything yet (update: check the list here).

In the meantime, you can confirm if your device has received the update by going to the Store > install the Upgrade Advisor app > run the app to see if the update is available, and then select Enable Windows 10 upgrade.

Here’s the complete announcement that has been posted by Microsoft’s CVP Windows and Devices Group Core Quality Michael Fortin:

Today, we’re pleased to begin the roll-out of Windows 10 Mobile to select Windows Phone 8.1 devices. There are a lot of great new features in Windows 10 Mobile, like Continuum, Windows Hello and Cortana.

Consistent with our approach to the Windows 10 PC upgrade, we are focused on delivering a high quality experience for our customers. The Windows 10 Upgrade Advisor app can be downloaded from the Windows Store to see if the upgrade is available for your device.

You can see the current list of Windows Phone 8.1 devices that are supported for the upgrade to Windows 10 here.

This list includes a limited set of Windows Phone 8.1 devices and does not include some devices that are currently running Windows 10 Mobile in the Windows 10 Mobile Insider program. As Windows 10 delivers significant new innovations, many older devices are not able to successfully upgrade without an impact on the customer experience. Our goal is to only offer the Windows 10 upgrade to devices that we are confident can continue to deliver a good customer experience.
